The Fuel filter has three types: diesel filter, fuel filter and gas filter . The function of the fuel filter is to prevent particulate matter, water and impurities in the fuel, and to ensure that the precision parts of the fuel system are protected from wear and other damage. How to change fuel filter, choose YD filter, then you could save your fuel filter cost and fuel filter replacement cost.

The fuel filter is connected in series between the fuel pump and the inlet of the throttle body. The function of the fuel filter is to remove solid impurities such as iron oxide and dust contained in the fuel to prevent the fuel system from being clogged (especially the injector). Reduce mechanical wear, ensure stable engine operation and improve reliability. The structure of the oil burner consists of an aluminum shell and a bracket with stainless steel inside. The bracket is equipped with high-efficiency filter paper sheets, and the filter paper sheets are formed in a chrysanthemum shape to increase the flow area. The EFI filter cannot be used with a carburetor filter. Since the EFI filter is often subjected to a fuel pressure of 200-300 KPA, the filter's compressive strength is generally required to be above 500 KPA, and the carburetor filter does not have to reach such a high pressure.

The structure of the diesel filter is roughly the same as that of the oil filter, and it is available in both exchangeable and spin-on versions. However, the working pressure and oil temperature requirements are much lower than that of the oil filter, and the filtration efficiency requirements are much higher than the oil filter. The filter element of the diesel filter is mostly made of filter paper, and it is also made of felt or polymer material.

Diesel filters can be further divided into diesel water separators and diesel fine filters. An important function of the oil-water separator is to separate the water in the diesel. The presence of water is extremely harmful to the diesel fuel supply system, and rust, wear, jamming and even worsening the combustion process of diesel. Due to the high sulfur content in China's diesel fuel, even when it is burned, it will react with water to form sulfuric acid to corrode engine parts. The traditional method of water removal is mainly precipitation, passing through the funnel structure. Engines with more than three national standards put forward higher requirements for water separation, and high requirements require high-performance filter media.

The diesel fine filter is used to filter fine particles in diesel. The diesel engine discharged from the third or third country is mainly for the filtration efficiency of 3-5 micron particles.
